Figure 3From: Faking photon number on a transition-edge sensorHistogram of TES output voltage under weak-coherent laser illumination at \(1550~\text{nm}\) (red), \(780~\text{nm}\) (black), and \(450~\text{nm}\) (blue). The leftmost peak represents zero-photon detection. Subsequent peaks to the right represent higher photon number detections. These peaks appear at the voltage level proportional to the energy of the photonsBack to article page
